ab170190 - Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.


  • 功能Plays a role in cell adhesion, and in cohesion of the endothelial monolayer at intercellular junctions in vascular tissue. Its expression may allow melanoma cells to interact with cellular elements of the vascular system, thereby enhancing hematogeneous tumor spread. Could be an adhesion molecule active in neural crest cells during embryonic development. Acts as surface receptor that triggers tyrosine phosphorylation of FYN and PTK2, and a transient increase in the intracellular calcium concentration.
  • 组织特异性Detected in endothelial cells in vascular tissue throughout the body. May appear at the surface of neural crest cells during their embryonic migration. Appears to be limited to vascular smooth muscle in normal adult tissues. Associated with tumor progression and the development of metastasis in human malignant melanoma. Expressed most strongly on metastatic lesions and advanced primary tumors and is only rarely detected in benign melanocytic nevi and thin primary melanomas with a low probability of metastasis.
  • 序列相似性Contains 3 Ig-like C2-type (immunoglobulin-like) domains.
    Contains 2 Ig-like V-type (immunoglobulin-like) domains.

Anti-CD146 antibody [P1H12] 图像

  • IHC image of CD146 staining in human aorta formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab24577, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

    Goat polyclonal Secondary Antibody to Mouse IgG - H&L (HRP), pre-adsorbed at 1/5000 dilution

    Performed under reducing conditions.

    Predicted band size : 72 kDa
    Observed band size : 110 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 55 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 20 minutes
    This blot was produced using a 10% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 3% Milk before being incubated with ab24577 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution.
  •  ab24577 at 1/1000 dilution staining mouse brain tissue sections by Immunohistochemistry (Frozen sections). Mice were processed by transcardial perfusion first with saline, then 4% PF. After overnight incubation in 4% PF, brains were transfered to sucrose. Upon saturation, brains were frozen, sectioned with a cryostat, and then the sections were immediately mounted on slides. The tissue was incubated with ab24577 for 2 hours and then an Alexa Fluor ® 594 goat anti-mouse IgG was used as the secondary (red). DAPI staining is shown in blue. Images were taken with a confocal microscope in comparable cortex regions of the lesion or contralateral side in the same section. The lesion image shown is from this model of ischemia-hypoxia, with 1 hour of recovery time after injury, when endothelial cell activation is quite robust.

  • ab24577 staining CD146 in murine bone marrow leukocytes by Immunocytochemistry/ Immunofluorescence. The cells were fixed in methanol and then blocked using 5% serum for 2 hours at 25°C. Samples were then incubated with the primary antibody at 1/400 for 12 hours at 4°C. The secondary antibody used was a goat anti-mouse IgG conjugated to Alexa Fluor® 594 (red) used at a 1/500 dilution.

  • Flow cytometry analysis of hBMSCs cultured in complete a-MEM supplemented with 1 ng/mL TGF-ß1 for 7 days, staining CD146 with ab24577.

    Cells were trypsinized, counted and resuspended in 2% BSA at a concentration of 2500 cells/µL. Cells were first incubated for 45 min at 4°C, protected from light, with primary antibody antibody (1/100). Cells were then incubated for 45 minutes, protected from light, at room temperature with AlexaFluor®488-conjugated goat anti-mouse secondary antibody (1/500).
